A signer forwards one email; the result is a self-contained evidence bundle (a single PDF) that anyone can verify on their own machine, even offline, even if this service disappears. DKIM alone isn't durable evidence, so kysigned never relies on it alone: each signature is timestamped twice at receipt, and its DKIM key is pinned in a public timestamped archive. Later key rotation, or even a provider publishing its old private keys, can't retroactively forge or deny a signature (details: docs/trust-model.md). Quick Start 1. Sign a document right now (no setup) Sign documents at kysigned.com. Buy credits, send. No install, no SDK. 2. Deploy your own kysigned is a complete, self-hostable app: clone it, point it at your own run402 project (managed email + DB + compute), and you're operating your own instance. All run402 I/O goes through @run402/sdk . That command reads run402.json , creates or links a Run402 project, creates the forward-to-sign and notifications mailboxes, sets generated runtime secrets, runs the local build, deploys the database/site/function release, and verifies the app. See docs/run402-cloud.md for the detailed runbook and smoke-test checklist.
